Value Collection BS260000S Jobber Drill Bit Letter S Hss

Product Description

The VALUE COLLECTION BS260000S is a letter-size S jobber drill bit machined from high speed steel (HSS) for general-purpose drilling in a wide range of materials. The 140-degree split point geometry with web thinning reduces walking on entry and lowers thrust force, making it well-suited for production and maintenance drilling. At 4.875 inches overall length with a 3.5-inch fast-spiral flute, the bit clears chips efficiently and maintains concentricity through the cut. The bright, uncoated finish keeps surface hardness consistent across the HSS substrate. This is a standard straight-shank jobber drill sized at 0.3480 inches, conforming to ANSI specification.

This drill bit is designed for right-hand cutting in steel, aluminum, non-ferrous metals, and wood. It is used in machine shops, maintenance facilities, and field service applications wherever a letter-S diameter hole is required. The straight cylindrical shank seats directly in standard three-jaw drill chucks and quick-change holders without adapters. The fast spiral flute profile makes it a practical choice for softer metals and wood where fast chip evacuation matters. Machinists, millwrights, pipefitters, and general maintenance technicians will find it a reliable stock item for everyday drilling tasks.

Key Features

• Letter S diameter — 0.3480 inches — conforming to ANSI jobber-length specification
• 140-degree standard point with web thinning reduces entry walking and lowers axial thrust
• High speed steel construction provides adequate hardness for steel, aluminum, non-ferrous metals, and wood
• Fast spiral flute design promotes efficient chip evacuation, especially in softer workpiece materials
• Bright, uncoated finish — no added coating to chip or delaminate during regrinding
• Straight cylindrical shank fits standard drill chucks without adapters
• Two-flute geometry with tapered web configuration for balanced cutting action

Compatibility

Designed as a general-purpose jobber drill for use in any standard drill press, hand drill, or CNC machining center equipped with a chuck or collet sized for a 0.3480-inch straight shank. Compatible with workpiece materials including steel, aluminum, non-ferrous metals, and wood as noted in the manufacturer specification.

Installation Notes

Secure the shank fully in a properly sized drill chuck or collet before operation and verify chuck key is removed before starting the spindle. Use appropriate cutting fluid or coolant when drilling steel to extend tool life, even though this bit does not feature through-coolant capability. Inspect the cutting edges for wear before each use; a dull drill bit increases thrust load and can cause workpiece damage or breakage. Regrinding to the original 140-degree point geometry restores cutting performance.
